Which subatomic particle plays the greatest part in determining the properties of an element?
2 answers:
Explanation:
Every atom consists of three sub-atomic particles which are protons, neutrons and electrons.
Inside the nucleus of an atom, there will be only protons and neutrons. Whereas electrons revolve around the nucleus of an atom.
But in a chemical reaction it is only the electrons that are able to participate. Whereas protons and neutrons only participate in nuclear reactions and not in any chemical reactions.
For example,
These electrons help in determining the reactivity of a substance because every atom wants to attain stability. Hence, they react with other atoms according to their number of valence electrons.
Thus, we can conclude that electrons are the subatomic particle plays the greatest part in determining the properties of an element.

Answer: The final pressure will decrease ad the value is 85 kPa
Explanation:
To calculate the final pressure of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
where,
are the initial pressure and temperature of the gas.
are the final pressure and temperature of the gas.
We are given:
Putting values in above equation, we get:
Hence, the final pressure will decrease ad the value is 85 kPa
